This summer, ESPN.com is taking a closer look at each scholarship player on the Oklahoma Sooners' roster in our Crimson Countdown series. Each day, we analyze each player’s impact on the program since arriving on campus, his potential impact this fall, and his long-term projection. Starting with No. 1 Dominique Alexander, the series follows the roster numerically through No. 98 Chuka Ndulue.

No. 94 Torrea Peterson, defensive tackle, 6-foot-3, 300 pounds, senior

Impact thus far: Peterson had the most productive season of his career with seven games played and one start with four total tackles in 2013. He hasn’t made a major impact with 13 career games (one start) and seven tackles including 1.5 tackles for loss during his career.

Impact in 2014: Peterson is one of the reasons the Sooners could have the Big 12’s top defensive line. He’s not slated to start but he provides veteran competition and little drop off if called upon this fall. He’a a quality option for OU’s defensive line rotation.

Long term upside: He should be a contributor during his final season.

Evaluation grade for Peterson: D. More is expected from a three-star signee who has been on campus for four years. One start in 13 career games isn’t good enough. Peterson has done some things to keep himself off the field early in his career but if he continues to improve like he did heading into his junior season this grade would jump to an C.

Development grade for Peterson: B. There’s not much more the Sooners could have done to develop Peterson. They redshirted him and waited for him to mature before he finally became a contributor as a junior.
